Q: Why isn't sigc++config.h installed with the rest of the headers?
|
||
|
|
|
||
|
|
A: Traditionally include files that are dependent on the compiler
|
||
|
|
or srchitecture belong under lib trees and not the include tree.
|
||
|
|
This allows machines to share include directories on large multiuser
|
||
|
|
systems.
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.57/include
|
||
|
|
/usr/lib/glib/include
|
||
|
|
/usr/lib/qt/include
|
||
|
|
|
||
|
|
To access that file you should include a -I PREFIX/lib/sigc++/include
|
||
|
|
in your compiler switchs.
|
||
|
|
|
||
|
|
This can be done for you automatically through the use of
|
||
|
|
the sigc-config script.
|
||
|
|
|
||
|
|
c++ myfile.cc `sigc-config --cflags --libs`
|
||
|
|
|
||
|
|
Last, if you really don't like this just symlink the file into
|
||
|
|
PREFIX/include. (Don't copy or the next version of libsigc++
|
||
|
|
very likely won't work right!)
|
||

Q: Why on Visual C++ can do I get piles of errors when trying to
|
||
|
|
use classes which contain Signals?
|
||
|
|
|
||
|
|
A: Visual C++ requires all classes which are parameterized to be
|
||
|
|
explicitely exported. This is the same problem encountered
|
||
|
|
when using STL classes in VC++. Microsoft Knowledge Base
|
||
|
|
article Q168958 contains the solution.
|
||
|
|
|
||
|
|
(http://support.microsoft.com/support/kb/articles/Q168/9/58.ASP)
|
||
|
|
|
||
|
|
You will need to create an export file with all the signals,
|
||
|
|
slots, and parameterized functions explicitely instantiated
|
||
|
|
and include it in your library source. (Anyone have an example
|
||
|
|
of this?)
